Hi there, I agree with Zoom & otch, it sounds to me like he's just restless because he's used to a certain level of exercise, and isn't getting it... sounds almost like he's trying to turn everything into a game, even when you're being serious about what you want him to do

I've noticed that Moro will get a lot more playful and puppy-like indoors, and tend to listen less when she doesn't get to go on a long walk or a run... she usually gets one every day, but I've been sick lately and haven't been able to take her as far, and when the weather gets really cruddy she definitely finds ways to take out her energy in the house

I'd say Ruckus will just have to be patient about the exercise until your leg is better, and you'll have to be patient with him, it's probably just stressful on both of you to have to be cooped up inside more than usual.
